- a direction in which the outer peripheral-side engagement portion comes into engagement with the first engagement portion and a direction in which the inner peripheral-side engagement portion comes into engagement with the second engagement portion are the same, that is, from the outer peripheral side to the inner peripheral side. Therefore, when the door glass is closed, the glass run integral molding is pushed up from the inner peripheral side to the outer peripheral side to weaken both an engagement force of the outer peripheral-side engagement portion to the first engagement portion and an engagement force of the inner peripheral-side engagement portion to the second engagement portion. As a result, the glass run integral molding is more likely to be undesirably removed from the door frame.

- a firm engagement force to the door frame can be obtained by the one of (hard-resin side) of the outer peripheral-side engagement portion and the inner peripheral-side engagement portion.
- assembly ease of the glass run integral molding to the door frame can be obtained by the another one (soft-resin side) of the outer peripheral-side engagement portion and the inner peripheral-side engagement portion.
- the glass run integral molding includes at least one of: a first reinforcing lip having a distal end portion for coming into elastic engagement with the door frame to enhance an elastic engagement force of the outer peripheral-side engagement portion to the first engagement portion; and a second reinforcing lip having a distal end portion for coming into elastic engagement with the door frame to enhance an elastic engagement force of the inner peripheral-side engagement portion to the second engagement portion.
- assembly strength of the glass run integral molding to the door frame can be enhanced.
- the door frame is formed by bending a thin steel plate so that the flange portion has a triple-layered structure in which an intermediate plate, an outer peripheral-side plate, and an inner peripheral-side plate are laminated.
- the first engagement portion is configured by a concave portion formed by protruding a car inner-side portion of the intermediate plate to the inner peripheral side and an end portion of the outer peripheral-side plate, which is provided so as to partially overlap the concave portion.
- the second engagement portion is configured by a projecting portion formed on the inner peripheral-side plate so as to correspond to the concave portion to project to the inner peripheral side.
- the protruding portion for forming the concave portion can be located in the concave portion for forming the projecting portion. Therefore, a space for configuring the first engagement portion and the second engagement portion can be made small. Accordingly, the door frame can be reduced in size as well as in weight.
- the door frame may be formed by bending a thin steel plate so that the flange portion has a triple-layered structure in which an intermediate plate, an outer peripheral-side plate, and an inner peripheral-side plate are laminated

- the second engagement portion may be configured by a second convex portion formed by bending a car inner-side portion of the inner peripheral-side plate to the inner peripheral side and then folding the car inner-side portion.
- the flange portion of the door frame has the double-layered structure of the thin steel plate. Therefore, as compared with the case where the flange portion has the triple-layered structure of the thin steel plate, the weight of the door frame can be reduced. Moreover, an operation of firmly fixing a lower end portion of the door frame to the door panel (for example, a door inner panel) at the flange portion (for example, an operation of spot-welding three layers of the steel plate, including the door inner panel and the thin steel plate having the double-layered structure) can be easily performed as compared with an operation performed in the case where the flange portion has the triple-layered structure of the thin steel plate (for example, an operation of spot-welding four layers of the steel plate, including the door inner panel and the thin steel plate having the triple-layered structure).

Description
- The present invention relates to a glass run integral molding adapted to be assembled to a door frame surrounding a window opening of a vehicle door and a door frame structure including the glass run integral molding and the door frame.
- A glass run integral molding (a molding with which a glass run is integrated) to be assembled to a door frame surrounding a window opening of a vehicle door is described in, for example, JP 2005-153581 A. The glass run integral molding, which is described in JP 2005-153581 A, includes an outer peripheral-side side wall portion and an inner peripheral-side side wall portion, a car outer-side side wall portion, a glass run portion, and a body seal lip portion in an integrated manner. The outer peripheral-side side wall portion and the inner peripheral-side side wall portion sandwich a flange portion formed on an upper part of a door frame. The car outer-side side wall portion connects a car outer-side end portion of the outer peripheral-side side wall portion and that of the inner peripheral-side side wall portion to each other and extends along a door glass surface. The glass run portion is formed so as to extend from the inner peripheral-side side wall portion and the car outer-side side wall portion to seal a peripheral edge of a door glass. The body seal lip portion is formed so as to extend from the outer peripheral-side side wall portion to an outer peripheral side to seal a clearance between a vehicle door and a vehicle body. The glass run integral molding also includes an outer peripheral-side engagement portion and an inner peripheral-side engagement portion in an integrated manner. The outer peripheral-side engagement portion is formed so as to extend from the outer peripheral-side side wall portion to come into elastic engagement with a first engagement portion formed on the outer peripheral side of the flange portion of the door frame from the outer peripheral side. The inner peripheral-side engagement portion is formed so as to extend from the inner peripheral-side side wall portion to come into elastic engagement with a second engagement portion formed on the door frame from the outer peripheral side.
- According to the glass run integral molding described in JP 2005-153581 A mentioned above, a direction in which the outer peripheral-side engagement portion comes into engagement with the first engagement portion and a direction in which the inner peripheral-side engagement portion comes into engagement with the second engagement portion are the same, that is, from the outer peripheral side to the inner peripheral side. Therefore, when the door glass is closed, the glass run integral molding is pushed up from the inner peripheral side to the outer peripheral side to weaken both an engagement force of the outer peripheral-side engagement portion to the first engagement portion and an engagement force of the inner peripheral-side engagement portion to the second engagement portion. As a result, the glass run integral molding is more likely to be undesirably removed from the door frame.
- The present invention has been made to solve the above-mentioned problem, and provides a glass run integral molding adapted to be assembled to a door frame surrounding a window opening of a vehicle door, including: an outer peripheral-side side wall portion and an inner peripheral-side side wall portion for sandwiching a flange portion provided to the door frame; a car outer-side side wall portion for connecting a car outer side end portion of the outer peripheral-side side wall portion and a car outer side end portion of the inner peripheral-side side wall portion to each other and extending along a door glass surface; a glass run portion formed so as to extend from the inner peripheral-side side wall portion and the car outer-side side wall portion to seal a peripheral edge of a door glass; a body seal lip portion formed so as to extend from the outer peripheral-side side wall portion toward an outer peripheral side to seal a clearance between the vehicle door and a vehicle body; an outer peripheral-side engagement portion formed so as to extend from the outer peripheral-side side wall portion, for coming into elastic engagement with a first engagement portion formed on an outer peripheral side of the door frame from the outer peripheral side; and an inner peripheral-side engagement portion formed so as to extend from the inner peripheral-side side wall portion, for coming into elastic engagement with a second engagement portion formed on an inner peripheral side of the door frame from the inner peripheral side.
- For carrying out the present invention described above, the glass run portion and the body seal lip portion may be made of a soft resin, the outer peripheral-side side wall portion, the inner peripheral-side side wall portion, and the car outer-side side wall portion may be made of a hard resin harder than the soft resin, at least a part of one of the outer peripheral-side engagement portion and the inner peripheral-side engagement portion may be made of the hard resin, and another one of the outer peripheral-side engagement portion and the inner peripheral-side engagement portion may be made of the soft resin. Further, the glass run integral molding according to the present invention may include at least one of: a first reinforcing lip having a distal end portion for coming into elastic engagement with the door frame to enhance an elastic engagement force of the outer peripheral-side engagement portion to the first engagement portion; and a second reinforcing lip having a distal end portion for coming into elastic engagement with the door frame to enhance an elastic engagement force of the inner peripheral-side engagement portion to the second engagement portion.
- Further, the present invention provides a door frame structure, including: a door frame having a flange portion and surrounding a window opening of a vehicle door; and a glass run integral molding to be assembled to the door frame, including: an outer peripheral-side side wall portion and an inner peripheral-side side wall portion for sandwiching the flange portion of the door frame; a car outer-side side wall portion for connecting a car outer-side end portion of the outer peripheral-side side wall portion and a car outer-side end portion of the inner peripheral-side side wall portion to each other and extending along a door glass surface; a glass run portion formed so as to extend from the inner peripheral-side side wall portion and the car outer-side side wall portion to seal a peripheral edge of a door glass; a body seal lip portion formed so as to extend from the outer peripheral-side side wall portion toward an outer peripheral side to seal a clearance between the vehicle door and a vehicle body; an outer peripheral-side engagement portion formed so as to extend from the outer peripheral-side side wall portion, for coming into elastic engagement with a first engagement portion formed on an outer peripheral side of the door frame from the outer peripheral side; and an inner peripheral-side engagement portion formed so as to extend from the inner peripheral-side side wall portion, for coming into elastic engagement with a second engagement portion formed on an inner peripheral side of the door frame from the inner peripheral side.
- It is preferred that the door frame be formed by bending a thin steel plate so that the flange portion has a triple-layered structure in which an intermediate plate, an outer peripheral-side plate, and an inner peripheral-side plate are laminated. In this case, it is preferred that the first engagement portion be configured by a concave portion formed by protruding a car inner-side portion of the intermediate plate to the inner peripheral side and an end portion of the outer peripheral-side plate, which is provided so as to partially overlap the concave portion, and that the second engagement portion be configured by a projecting portion formed on the inner peripheral-side plate so as to correspond to the concave portion to project to the inner peripheral side.
- According to the glass run integral molding and the door frame structure of the present invention, the outer peripheral-side engagement portion is configured to come into elastic engagement with the first engagement portion formed on the outer peripheral side of the door frame from the outer peripheral side, whereas the inner peripheral-side engagement portion is configured to come into elastic engagement with the second engagement portion formed on the inner peripheral side of the door frame from the inner peripheral side. Specifically, a direction in which the outer peripheral-side engagement portion comes into engagement with the first engagement portion and a direction in which the inner peripheral-side engagement portion comes into engagement with the second engagement portion are opposite to each other and therefore, are opposed to each other. According to this configuration, when the door glass is closed and the glass run integral molding is pushed up from the inner peripheral side to the outer peripheral side, an engagement force of the inner peripheral-side engagement portion to the second engagement portion is strengthened, although an engagement force of the outer peripheral-side engagement portion to the first engagement portion is weakened. As a result, an engagement force of the glass run integral molding to the door frame is maintained.
- For carrying out the present invention, the glass run portion and the body seal lip portion are made of a soft resin. The outer peripheral-side side wall portion, the inner peripheral-side side wall portion, and the car outer-side side wall portion are made of a hard resin harder than the soft resin. At least a part of one of the outer peripheral-side engagement portion and the inner peripheral-side engagement portion is made of the hard resin, whereas another one of the outer peripheral-side engagement portion and the inner peripheral-side engagement portion is made of the soft resin. In this case, desired sealability can be obtained by the glass run portion and the body seal lip portion. In addition, desired design (external shape) can be ensured by the outer peripheral-side side wall portion, the inner peripheral-side side wall portion, and the car outer-side side wall portion. Moreover, a firm engagement force to the door frame can be obtained by the one of (hard-resin side) of the outer peripheral-side engagement portion and the inner peripheral-side engagement portion. In addition, assembly ease of the glass run integral molding to the door frame can be obtained by the another one (soft-resin side) of the outer peripheral-side engagement portion and the inner peripheral-side engagement portion.
- For carrying out the present invention, the glass run integral molding includes at least one of: a first reinforcing lip having a distal end portion for coming into elastic engagement with the door frame to enhance an elastic engagement force of the outer peripheral-side engagement portion to the first engagement portion; and a second reinforcing lip having a distal end portion for coming into elastic engagement with the door frame to enhance an elastic engagement force of the inner peripheral-side engagement portion to the second engagement portion. In this case, assembly strength of the glass run integral molding to the door frame can be enhanced.
- Moreover, for carrying out the present invention, the door frame is formed by bending a thin steel plate so that the flange portion has a triple-layered structure in which an intermediate plate, an outer peripheral-side plate, and an inner peripheral-side plate are laminated. The first engagement portion is configured by a concave portion formed by protruding a car inner-side portion of the intermediate plate to the inner peripheral side and an end portion of the outer peripheral-side plate, which is provided so as to partially overlap the concave portion. The second engagement portion is configured by a projecting portion formed on the inner peripheral-side plate so as to correspond to the concave portion to project to the inner peripheral side. In this case, the protruding portion for forming the concave portion can be located in the concave portion for forming the projecting portion. Therefore, a space for configuring the first engagement portion and the second engagement portion can be made small. Accordingly, the door frame can be reduced in size as well as in weight.
- Further, for carrying out the present invention, the door frame may be formed by bending a thin steel plate so that the flange portion has a triple-layered structure in which an intermediate plate, an outer peripheral-side plate, and an inner peripheral-side plate are laminated, the first engagement portion may be configured by at least one of a convex portion and a concave portion respectively formed by protruding a car inner-side portion of the outer peripheral-side plate to a car inner side and a car outer side, and the second engagement portion may be configured by at least one of a second convex portion and a second concave portion formed by bending a car inner-side portion of the intermediate plate to the inner peripheral side and protruding the car inner-side portion to the car inner side and the outer peripheral side, and an end portion of the inner peripheral-side plate, which is bent to the inner peripheral side so as to partially overlap the second convex portion. In this case, a waterproof configuration of the door frame can be improved (for example, a waterproofing seal lip portion can be omitted) by the glass run integral molding. Thus, cost of the glass run integral molding can be reduced.
- Further, for carrying out the present invention, the door frame may be formed by bending a thin steel plate so that the flange portion has a double-layered structure in which an outer peripheral-side plate and an inner peripheral-side plate are laminated, the first engagement portion may be configured by at least one of a convex portion and a concave portion respectively formed by protruding a car inner-side portion of the outer peripheral-side plate to a car inner side and a car outer side, and the second engagement portion may be configured by a second convex portion formed by bending a car inner-side portion of the inner peripheral-side plate to the inner peripheral side and then folding the car inner-side portion.
- In this case, the flange portion of the door frame has the double-layered structure of the thin steel plate. Therefore, as compared with the case where the flange portion has the triple-layered structure of the thin steel plate, the weight of the door frame can be reduced. Moreover, an operation of firmly fixing a lower end portion of the door frame to the door panel (for example, a door inner panel) at the flange portion (for example, an operation of spot-welding three layers of the steel plate, including the door inner panel and the thin steel plate having the double-layered structure) can be easily performed as compared with an operation performed in the case where the flange portion has the triple-layered structure of the thin steel plate (for example, an operation of spot-welding four layers of the steel plate, including the door inner panel and the thin steel plate having the triple-layered structure).

The second engagement portion C2 is configured by the projecting portion Cb formed on the inner peripheral-side plate 11b 3 so as to correspond to the concave portion Ca to project to the inner peripheral side so that the concave portion Ca is partially present therein. Therefore, the concave portion Ca, which protrudes to the inner peripheral side, can be provided so as to be present in the concave portion formed by the projecting surface and an opposite surface of the projecting portion Cb. Accordingly, a space for configuring the first engagement portion C1 and the second engagement portion C2 can be reduced. As a result, thedoor frame 10 can be reduced in size as well as in weight. - In the first embodiment described above, an example where the part (see
FIG. 2 ) of the outer peripheral-side engagement portion 26 is made of the soft resin, the other part (seeFIG. 3 ) of the outer peripheral-side engagement portion 26 is made of the hard resin, and the inner peripheral-side engagement portion 27 is entirely made of the soft resin has been described.
